Pull low-voltage Class 2 (PELV) wiring for system communications.
• Must be daisy-chained.
• Must be less than 2000 feet (600m).
• Must run seperately from line (mains) voltage.

Include one extra #18AWG (1.0mm2).
Used as a “sense line” for emergency
(essential) lighting.
Wallstations
Four wires1 for low-voltage type Class 2 (PELV)
• Two #12 AWG (2.5mm2) conductors for control wiring.
• One shielded, twisted pair #18 AWG (1.0mm2) for data link.
1 If you use Lutron cable, you can use smaller gauge wires.
• If your total system is less than 500 feet (150m), you can use GRX-CBL-346S:
- Two #18AWG (1.0mm2) for power.
- One twisted, shielded pair #22AWG (.625mm2) for data link.
- No “sense line” included - add your own #18AWG (1.0mm2).
• If your total system is 500 to 2000 feet (150 to 600m), you can use GRX-CBL-46L:
- Two #12AWG (2.5mm2) for power.
- One twisted, shielded pair #22AWG (.625mm2) for data link.
- One #18AWG (1.0mm2) for sense line between Panels.
• Lutron has also approved smaller gauge cable from Belden, Liberty, Alpha, and Signature.
Ask for Lutron GRAFIK Eye Cable.

Connect Drain/Shield as shown. Terminate only at Power Panel if
Drain Terminal is provided. It is easiest to connect the bare drain
wires and cut off the outside shield throughout the control link.
Lutron recommends you make all connections in the Control Unit’s
wallbox. Remote connections must be in a switchbox or junction
box with a maximum wire length of 8 ft. (2.5m) from the link to
the connected unit.
